A sound quality customization system using Paired Comparison

This paper proposes a sound quality customization method based on an Paired Comparison interactive genetic algorithm (PC-IGA). A user who is not familiar with music and/or audio devices finds it difficult to customize the reproduction parameters to suit his/her preferences. Our solution is a system that customizes the reproduction parameters for headphone use by an intuitive user input panel; the IGA analyzes the user´s inputs and generates the appropriate parameters. The system makes it easy, even for novices, to obtain the preferred sound quality. Here, “sound quality” means a tone. In this paper, the proposed system simplifies the evaluation by using pair comparison. Results of a subjective assessment experiment for one sound sample demonstrate the possibility that the preferred sound quality can be obtained through this system.
